A doctor for the defense team for a 25-year-old man accused of triggering a security scare said the man was "off his meds" when he left a backpack near the finish line of the Boston Marathon Tuesday night.

Kevin Edson, who also goes by the name Kayvon Edson, was in court Wednesday on charges including disturbing the peace, disorderly conduct, disturbing a public assembly, possession or use of a hoax device and making a false bomb threat. He was held on $100,000 bail and sent to Bridgewater State Hospital for an evaluation.

On Tuesday evening, a police officer assigned to Copley Square noticed a man walking down the street barefoot, and when the officer asked him what was in the backpack, police said the man replied "a rice cooker."

"One of my officers assigned at Copley Square noticed a man walking down Boylston Street barefoot with a coat on and a knapsack, acting suspiciously. Walked up to him, asked him what was in the backpack? At that time, he stated that there was a rice cooker in the backpack," Boston Police Supt. Randy Halstead said.

A second bag was also found.

Edson's mother, Joie Edson, said her son has a mental disorder. She told The Associated Press that her son has bipolar disorder.

The bombs that exploded at the Boston marathon one year ago were made from pressure cookers.

The bomb squad investigated in the area of Boylston and Exeter streets, and just before 9 p.m. officials destroyed the first bag. The second bag was destroyed about an hour later.

The second bag was later determined to belong to a media outlet.

Police said there was no evidence that there were explosives in the backpacks, but they were destroyed as a precaution.

According to witnesses at the scene, the man who dropped the backpack was wearing a black veil and makeup on his face.

Boston police urged people to avoid the area during the investigation and Green Line trains were told to skip over Copley during the investigation.

Once the investigation concluded and the all clear was given, the area was reopened and Green Line trains were allowed to stop.
